Rotary evaporator (or rotavap/rotovap) is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation. Rotary evaporator is the use of stepless speed control glass rotating bottle constant speed rotation, the material in the bottle wall to form a large area uniform film, and then by the intelligent constant temperature water bath on the rotating bottle of uniform heating, vacuum conditions, high-speed evaporation, Efficient glass condenser cooling, recovery in the collection bottle. Rotary evaporator is the necessary basic instrument for chemical industry, medicine industry, institutions of higher learning and scientific research laboratory and other units, it is the main means for manufacturing and analyzing experiments when they do extraction and concentration .
2. Feature
Rotators consists of a set of stable and reliable micro motor, speed motor and integrated circuit control device. In the role of electronic speed, it can rotating steadily in 10-180 RPM range, it has reached the advanced level at home and abroad.
1,the move up and down lift system adopts motor revolved lifting structure.
2,the condenser adopted two kinds of optional structure , one is double line convection principle, the other one is a single line with interlayer water, ice, and dry ice container. Used in organic solvent evaporation. And the vertical condenser saves space.
3, the axis of rotation use high temperature high borosilicate glass, heat resistant and good sealing. Sealing parts use teflon + teflon two-way sealing, and the effect is good.
4, it is equipped with heating trough, and built-in resistance wire heater, heating temperature is from room temperature to 99 ºC.
5, the device is equipped with temperature indicator, intelligent temperature controlling, digital display, temperature control implemented by PT100 sensors. When the water temperature reaches primary temperature, the controller automatically cut off the heater power; When is lower than the water, temperature controller automatically turn on the heater power; To realize the tank water temperature be constant.
6, B type, E type is equipped with speed display, can accurately display rotation speed, E type is LCD screens.
